QUESTION
I'd like to have a 2 column reveal.js slide where I can page through the slides in the left-hand column (ColA) while a video plays in the right-hand column (ColB). The slides accompany the video.
I have it laid out on this page but the contents in the iframe/ColA are not large enough to read. I've tried scaling it but it scales the entire containing div, making the two columns overlap, and does not just scale the contents of the iframe.
Another option is to do the slides like normal, where each slide contains a link to the embedded video. My worry there is that every one of the embedded videos will play at once once the page loads because it's a live stream - it seems like that might eat a lot of processing power as my computer tries to play the same embedded live stream in 30 different slides. When moving from Slide1 to Slide2, are embedded videos stopped?
The full git repo for this is here.
...ANSWER
Answered 2021-Jun-14 at 10:32I don't think the iframe will work very well for multiple reasons:
- The scaling problem that you already encountered. iframes are notoriously hard to scale, as the size has to be hardcoded when embedding them.
- The nested presentation will have its own navigation, so it wont be clear where to proceed with the presentation.
You also already anticipated teh next problem - when putting the same video on multiple slides indeed the video will "restart" - first the old video will fade out and then the new copy will fade in. This is because each slide is it's own self-contained HTML element. So this also won't do what you want.
Instead I would propose to use Fragments. Fragments are the way you can have individual elements on a page change without changing the whole slide (commonly used for making bullet points appear).
In your case you can implement your "sub slides" on the left side as individual fragments that appear on top of each other using the css classes fragment fade-in-then-out (to make them appear/disappear) and r-stack (to make them appear on top of each other). You can see an example on the "Layout" page in the documentation (the second one with cat pictures).
If you put all of your sub-slides as fragments, then you can just have your video embedded as normal on the right and it will play independently from the subslides changing. Once the last sub-slide is passed, the presentation will move on to the next real slide (stopping the video).
QUESTION
In this challenge, using javaScript you will create 3 classes
- Super class called
Animal. DogandCatclass which both extendsAnimalclass (a dog is an animal and a cat is an animal)DogandCatclass should only have 1 function, which is their own implementation of thesound()function. This is polymorphism- a
Homeclass. But we’ll talk about that later
ANSWER
Answered 2021-Jun-05 at 13:48Since 2015 there should be no more need to go through the pain of assigning prototype properties like that, and establish inheritance between two classes with such assignments.
I would suggest rewriting your code completely, and using the class syntax, where you don't need to explicitly do this inheritance fiddling with the prototype property:

QUESTION
So, I was just reading about the Visitor pattern and I found the back and forth between the Visitor and the Elements very strange!
Basically we call the element, we pass it a visitor and then the element passes itself to the visitor. AND THEN the visitor operates the element. What? Why? It feels so unnecessary. I call it the "back and forth madness".
So, the intention of the Visitor is to decouple the Elements from their actions when the same actions need to be implemented across all the elements. This is done in case we need to extend our Elements with new actions, we don't want to go into all those classes and modify code that is already stable. So we're following the Open/Closed principle here.
Why is there all this back-and-forth and what do we lose if we don't have this?
For example, I made this code that keeps that purpose in mind but skips the interaction madness of the visitor pattern. Basically I have Animals that jump and eat. I wanted to decouple those actions from the objects, so I move the actions to Visitors. Eating and jumping increases the animal health (I know, this is a very silly example...)
...ANSWER
Answered 2021-Jun-03 at 17:21The code in the OP resembles a well-known variation of the Visitor design pattern known as an Internal Visitor (see e.g. Extensibility for the Masses. Practical Extensibility with Object Algebras by Bruno C. d. S. Oliveira and William R. Cook). That variation, however, uses generics and return values (instead of void) to solve some of the problems that the Visitor pattern addresses.
Which problem is that, and why is the OP variation probably insufficient?
The main problem addressed by the Visitor pattern is when you have heterogenous objects that you need to treat the same. As the Gang of Four, (the authors of Design Patterns) states, you use the pattern when
"an object structure contains many classes of objects with differing interfaces, and you want to perform operations on these objects that depend on their concrete classes."
What's missing from this sentence is that while you'd like to "perform operations on these objects that depend on their concrete classes", you want to treat those concrete classes as though they have a single polymorphic type.
A period exampleUsing the animal domain is rarely illustrative (I'll get back to that later), so here's another more realistic example. Examples are in C# - I hope they're still useful to you.
Imagine that you're developing an online restaurant reservation system. As part of that system, you need to be able to show a calendar to users. This calendar could display how many remaining seats are available on a given day, or list all reservations on the day.
Sometimes, you want to display a single day, but at other times, you want to display an entire month as a single calendar object. Throw in an entire year for good measure. This means that you have three periods: year, month, and day. Each has differing interfaces:
QUESTION
This is my regex: https://regex101.com/r/fBq3Es/1
(audiência|sessão virtual)(?:.(?!audiência|sessão virtual|até))*([1-2][0-9]|3[0-1]|0?[1-9])\s*de\s*([^\s]+)\s*de\s*((19|20)?\d\d)(?:,|\s*)*(?:,|\s*)*(?:\S*)?(?:,|\s*)*([01]?[0-9]|2[0-3])(h|:|\s*horas*\s*e\s*|\s*horas*\s*)([0-5]?[0-9])?
It should pick something like this:
Lorem Ipsum Lorem Ipsum Lorem Ipsum Audiência em 24 de Julho de 2022 às 16:00 horas Lorem Ipsum Lorem Ipsum Lorem Ipsum
And extract the "24 de Julho de 2022 às 16:00 horas"
its taking only the "4 de Julho de 2022 às 16:00 horas" missing the first digit for some reason.
The problem is, "9 de Janeiro de 2021" (with no leading zeroes or any other numbers) is also a possible input and answer.
I asked this question a few days ago and got the answer that the logic for the date bit of my regex is working (but only when taken out of the larger expression) "([1-2][0-9]|3[0-1]|0?[1-9])", I've tried changing positions, different combinations, to make the zero fixed and add another or ([1-2][0-9]|3[0-1]|0[1-9]|[1-9]), none of them worked.
So why does it "Eat" the first day digit, when its inside the full expression?
A demo of it is running as said on regex101.com with the config set to ECMAScript (JavaScript) and global multiline and case insensitive.
As they questioned me where this is being used, this bit regex was taken from a workflow that has a text parser "Module" that accept regex with those configurations, I can only feed it a regex, no different programing languages allowed.

I have a simple minimum width format using printf like so
ANSWER
Answered 2021-May-21 at 14:55It would appear that the printf function is counting the escape sequence characters that set the colours as part of the output width. Adding the number of characters required for each colour format to the width specifier should fix the issue.

QUESTION
I took this code from a previously answered question and I am trying to expand it so that it works with E and PI when the String contains "E" and "PI". I don't really understand how the code works because I am pretty new to Java and the explanation on the original comment was not great (I have since lost the link to the comment unfortunately).
...ANSWER
Answered 2021-Jun-08 at 03:32The key to the solution is to modify the grammar to support your supported named constants. It is therefore a requirement (as your examples suggest) that named constants be in capital letters: A - Z (to distinguish between functions).
(The specified grammar is incomplete in that it does not specify the syntax of functions but the code suggests it is lower-case characters in a subset of trig and log functions.)
So, grammar is updated as:
QUESTION
class Animal{
void eat(Animal animal){
System.out.println("animal eats animal");
}
}
public class Dog extends Animal{
void eat(Dog dog){
System.out.println("dog eats dog");
}
public static void main(String[] args) {
Animal a = new Dog();
Dog b = new Dog();
a.eat(b);
b.eat(b);
}
}
ANSWER
Answered 2021-Jun-06 at 16:13It's based on the concept of Inheritance and Polymorphism
Overriding happens when the sub-class has the same signature methods as that of the superclass. In your code, in the below subclass *method, the parameter being passed is a Dog type object and in the superclass i.e Animal, the parameter passed is an Animal type object.
